In the sketch, a country singer (played by Hader) introduces a new song he wrote by way of a long story about his father. In the course of introducing the song, he brings out some unusual instruments and has a bit of interaction with his son (played by Bieber). The song and the story are supposed to be completely inappropriate to the venue, but not even Hader could have anticipated how badly the sketch would go.

This particular sketch was never aired on NBC. In fact, it was cut after the disastrous dress rehearsal, which is shown here. Everything that could go wrong, did go wrong. Props were missing, the lighting was off, the audience wasn't getting the jokes, Hader almost broke character, Bieber delivered the wrong line and part of the set almost collapsed on the young singer.

Hader may be gone from the show, but he recently sat down with "SNL" writers Rob Klein and John Solomon to relive this infamous moment in a sketch that Hader swears "killed" when it was performed at an "SNL" table read just days before.

It's worth noting that when Hader appeared on Howard Stern's show in May, he did not have kind words for the Biebs, saying, "Justin Bieber showed up with like 20 guys. He had a guy holding a slice of pizza. A guy holding a Diet Coke. Going around stage, you're trying to fight through all these people to get dressed."

Maybe all those guys are the reason Hader didn't have his funny hat in the sketch.
